Is it possible to run Selenium in the background?

Question

Python

When the selenium application is launched, the browser is also launched, is it possible to make the browser run "in the background"?

Answer 1

It is possible without a browser at all, in headless mode, that is, there is drawing, but in memory, and it does not reach direct rendering. That is, screenshots will also work, everything is the same, but without launching the GUI.
A flag is needed --headless, see the doc for the web driver for your framework

Answer 2

If you write in Python, then I use the following code:
options = webdriver.FirefoxOptions()
options.set_headless(True)
browser = webdriver.Firefox(options=options)
